Quaternary Stratigraphy and Sedimentology of the Kotra Section on the Betwa River, Southern Gangetic Plains, Uttar Pradesh
Bibliographic record
Abstract
Abstract Floodplain deposits are exposed in an about 29 m high cliff section at Kotra along the Betwa river, a tributary of the Yamuna river at the southern margin of the Gangetic Plains. The Betwa is a peninsular river originating in the Bundelkhand Craton parts of which are exposed as bedrock close to the section. The Betwa river is incised and bordered by an extensive zone of badland (dissected into gullies). The stratigraphic units comprise pedogenized floodplain muds and reworked carbonate gravels that fill small plains-fed channels. Gully fills of mud and gravel mark extensive degradational surfaces that divide the section into discontinuity-bounded units, currently of unknown duration and age. Closely spaced discontinuities low in the section may mark a former interfluve level, after which a thick floodplain succession accumulated up to the level of the modem clifftop. Presence of prominent discontinuities and thick floodplain deposits in the cliff sections suggest that the late Quaternary history of the southern plains is marked by cycles of channel incision and floodplain degradation and alluviation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
